Application filed September 14, 1911. Serial No. 649,301.

To all whom t may camera i Be it known that-I, McRoY Dn'VrnsE, a citizen of the United States, residing. at

` Fresno, in the'county of Fresno and State of California, have1 invented a new Aand useful Plow, .of which the ,following isa" specification. v

This invention relates to rotary plows and more particularly to machines of this type adapted to be propelled by motors, one of the objects of the invention being to provide a gang of rotary plows, said gang consisting ofmovably connected sections adapted to be adjusted angularly relative vto eachother. A further object is to provide a plow of this type. including supplemental frame carrying the' soil engaging devices, said frame being shiftable upwardly and downlwardly to produce a corresponding movement of the gang ofplows.

Another object is to provide rotary plows each of which includes a series of movably .mounted soil engaging devices having means for holding them yieldingly in operativepo'- sitions whereby, should .the ldevices, j move,V against an unyielding object, they would be free to yield and pass thereover, thus preventing injury to any partof the machine. Another Objectis to provide means for cleaning the plowsY during t-he operation thereof.

'With the'foregoing and other objects view which will appear .as the description proceedsthe invention resides in the combination and arrangement of parts and 1nthe details of construction hereinafter de s'cribed and claimed, it being understood that changes in the precise embodiment of the invention'herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. In the accompanying drawings the preferred form of the shown.

In said drawings z--F igure 1 is a plan View ofthe machine. i Fig-2 is a side elevation thereof. Fig. 3 is an enlarged side elevation of one of the'plows. Fig. 4 is afrol-'1t elevation of the plow shown in Fig. 3. Fig. 5 .is an enlarged sect-ion. through one of the.

plow cleaners, a to'othbeing lshown in .elevation. Fig.' 6 is a section on 'line A -B Fig.4 1. Fig. 7 isv anenlarged section through one of the end bearings of the shaft of the gang of plows.

-8 and swinging tongue 6 toward either side may be mounted on this platform.

linvention has been' Referring to .the figures by characters of arear axle 2 and a 'front or steering axle 3,

the rear Aaxl'being supported b v wheels Ll' and adapted to be rotated thereby while the lfront axle, which is supported by wheels 5 has a-tongue 6 extending rearwardly there-ff 7. 'Steering cables or chains 8 extend from therear end ofI tongue 6 tojguide' sheaves or sprockets 9 located'adj'acent the sides of the frame l, theseflexibleconnections being referenced' designa-tes the main frame of ythe machme, the-same being supported` byey from at its centerand suit-ably braced, as at f then extended' inwardly t-o a shaft 10 to.y

which they yare secured and about lwhich they are adapted tov be wound. A steeringv wheel 11 is secured on the. shaft 10 whereby the same can b e conveniently 'rotated for the purpose of shlfting the flexible connections of the frame. In this manner the machine can be guided while being propelled. A

vplatform'12 is mounted on'the frame land a motor, such as indicated generallyr at 13 A shaft 14 is journaledon andextends transversely of thefram'e 1 and receives motion, through .a `chain l5 'and 'sprockets 1G and 17, from the motor 13. This shaft 14 is engaged by bearings 1S secured on the front portion of a supplemental vframe 19 located under the. .main frame 1. apparent that the said supplemental frame can swing relative to'the main frame and with shaft' 14 as its axis, without, however,

It will thus beinterfering with the rotation of said' shaft. y

The sides of the frame are preferably bowed, as indicated at 20, and longitudinal beams 21 are arranged adjacent the center of the frame 19 and have a shaft section 22 journaled thereon. This shaft section is provided with a. series of rotary p'low's such'as' l indicated generally at 23, anda sprocket 24 is preferably secured to saidshaft and .receives motion, as through a chainv 25, from a sprocket 26 secured to the shaft 14. Each ico of the plows 23 consists of a ,disk 2l having ears 25 extending from its periphery 'and arranged in pairs, the ears of eachfpair be-A ing spacedV apart laterally so as to receive between them the shank 2Gof the plow point 27. An arm 28 extends from' the shank 26 determined and a spring29 is interposed between this arm and the-periphery of disk 24, thus serving -to hold the shank yieldingly in a pre- Any vdesired number or plows 23 may be secured to the shaft 'section 22 and the ends of this shaft section are connected, by uni versal .joints 30, to shaft sections 31 each ofn which is likewise provided with rotary plows 32,'similar in all respects to the plows hereinbefore described.- The outer ends of these shaft sections' 31 are journaled in bearings 33 supported by clips 34 which are slldahly mounted o.. the curved portions of the frame 19 and 'are adapted to be tightenedso as vto hold the bearings lagainst move' '.ment. The curved portions20 areconcen- .tric with the universal jointsBO so that the fsha'ft sect-ions 31 can be swung about said 'joints as pivots and their 'outer ends can be heldimany positions to which they may be n.djiisted, by tightening the clips 34. This adjustment of the shaft sections 31 will not,

however, interfere with their rotation as shaft section 22, when rotated, will always transmit lmotion to the shaft sections 31 through the universal joints 30.

- Aibar 35 is s'ecuredupon' the beams 21,

back of the shaft section 22 and is of the Same length as Said section.Y This bar 'has' c'lirved teethf'extending forwardly and downwardly therefrom-'and projecting4 loelikewise' formed with forwardly and downs afardly curved fingers 89-similar to the 1ingers 36 hereinbefore described. -Said fingers 39 project between .the-plows 32 on the shaft sections 3 1. will be apparent that, as 'the plows rotate, any 'trash carried. upwardly thereby will engage the lower concave faces .of the teeth 36 and will be dedectednoutwardly and rearwardly as indicated by the arrow in Fig. 5,'

thus being disengaged from the plows and deposited on the ifgfround. Clogging of the,

is thus prevented.

Motion istransmitted from' shaft 14 to the 'er axle 2 by a chain 40 mounted on a prccket 41 secured to .the rear axle 2 and on, a sprocket 42' secured to 'the shaft 14.'

'iayo of these chains may be provided, one being located at each side of the frame 1 and each chain being provided with sprockets 41' and 42.

.. A lifting shaft 43-is journaled upon the rear portion of frame -1 and has crank arms /l/'i at its ends connected, by links 45, to arms 46 extending vrearwardlyY from theframe 1 9. rank 47 is carried by shaft 48 at a point 48 to an operating lever 49.

between its ends' and is connected, by a-link shaft sections 't and the bars-.37 are adf By. pror'fiding these fingers it# Before starting the' machine forward, the' justed vrelative tothe shaft section 22 vand bar 35 so as to extend at any desired angles relative thereto. Lever 49 'is shifted so "as to rotate shaft 43 and lower' frame 19 thus to bring Jhe soil engaging devices 27 onto 'the'gro'und- The machine is then propelled forward motion being transmitted from the motor through chains 15 and 25 to the shafts 14 and '22' and, through chain 40 to 'the'rear axle 2. As the shaft section 22' andthe seotions 33 rotate the plow points 27 will bev brought successively into the ground and will turn the soil.

Should .the points come into contact with' unyielding' objects the I springs 29 will permit Said points to swing back and thus pass-'over saidobjects with' out causing injury to the plow.
